It is white, it has rows of passenger windows, and it got there under its own power on a runway of polished blue ice at Union Glacier, roughly 1,000 kilometres from the South Pole. Nobody bulldozed a strip for it. The wind did that, over centuries, by scouring the snow away until the glacier underneath was bare and hard enough to take a jet.<\/p>\r\n\r\n<p>Which makes the most-asked question about polar flying a slightly odd one. People type <em>why don\u2019t planes fly over Antarctica<\/em> into Google several thousand times a month, and the honest first answer is that they do. Not many, and almost never on a scheduled ticket, but they do.<\/p>\r\n\r\n<p>The real question underneath it is better: why is the Arctic threaded with busy airline routes while the Antarctic is, in commercial terms, empty? The answer is not a conspiracy, a no-fly zone or anything to do with the shape of the Earth. It is a stack of unglamorous regulatory and logistical facts, and the most interesting one is that a runway existing in Antarctica does not make it an airport you are allowed to plan on.<\/p>\r\n\r\n\r\n<div style=\"background:#f2f4f7;border-left:4px solid #5C91FF;padding:18px 22px;margin:26px 0\"><p style=\"margin:0 0 8px;font-weight:700;color:#0d1117;font-size:17px\">Quick Facts<\/p><ul style=\"margin:0;padding-left:18px;font-size:15px;line-height:1.7;color:#333\"><li style=\"margin:4px 0\"><strong>North Polar Area:<\/strong> Everything north of 78\u00b0 N (14 CFR 121.7)<\/li><li style=\"margin:4px 0\"><strong>South Polar Area:<\/strong> Everything south of 60\u00b0 S (14 CFR 121.7)<\/li><li style=\"margin:4px 0\"><strong>Compass unusable within:<\/strong> About 1,000 NM of each magnetic pole<\/li><li style=\"margin:4px 0\"><strong>Reliability threshold:<\/strong> Horizontal field below 6,000 nanotesla<\/li><li style=\"margin:4px 0\"><strong>Jet fuel freeze limits:<\/strong> \u221240 \u00b0C for Jet A, \u221247 \u00b0C for Jet A-1 (ASTM D 1655)<\/li><li style=\"margin:4px 0\"><strong>Survival kit:<\/strong> At least two cold-weather anti-exposure suits aboard<\/li><li style=\"margin:4px 0\"><strong>Passenger recovery:<\/strong> Expected within 48 hours of a diversion<\/li><li style=\"margin:4px 0\"><strong>Furthest south by a Qantas 787:<\/strong> 74.17\u00b0 S, QF28, 14 July 2023<\/li><\/ul><\/div>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">Two polar areas, drawn by two completely different rules<\/h2>\r\n\r\n<p>American regulations define both ends of the planet, and they do not define them symmetrically. Under 14 CFR 121.7, the North Polar Area is the entire area north of 78\u00b0 N. The South Polar Area is the entire area south of 60\u00b0 S. That is an eighteen-degree difference in where the special rules begin, and it is worth understanding why, because it tells you what each set of rules is actually for.<\/p>\r\n\r\n<p>The northern boundary is a navigation line. At 78\u00b0 N you are deep inside the region where a magnetic compass has stopped meaning anything, where meridians converge so sharply that headings change faster than the aircraft does, and where a diversion airport is a long way away. It is drawn where the physics gets difficult.<\/p>\r\n\r\n<p>The southern boundary is a political one. The Antarctic Treaty Area covers everything between 60\u00b0 and 90\u00b0 South \u2014 the same line, to the degree. The FAA does not publish its reasoning, but the coincidence is exact, and it means the South Polar Area starts hundreds of miles out over open ocean, well before anything physically difficult begins.<\/p>\r\n\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/SCQhIWsQJsI\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div>\r\n<p style=\"font-size:13px;color:#777;text-align:center;margin:-14px 0 24px;font-style:italic\">Half as Interesting on the north-versus-south asymmetry \u2014 the most-watched explainer on the question, with 4.4 million views.<\/p>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">The compass gives up first<\/h2>\r\n\r\n<p>A magnetic compass works by sensing the horizontal component of the Earth\u2019s magnetic field. Near either magnetic pole that horizontal component shrinks towards nothing, because the field is diving almost straight down into the ground. The FAA puts a number on the point of failure: when horizontal field strength falls below 6,000 nanotesla, the compass can no longer be considered reliable.<\/p>\r\n\r\n<p>In practice that draws a circle roughly 1,000 nautical miles wide around each magnetic pole. The FAA calls these Areas of Magnetic Unreliability, and an airline needs a specific authorisation \u2014 OpSpec B040 \u2014 before it may fly in one. The Northern AMU covers everything within 1,000 NM of the magnetic North Pole except Alaska and its territorial waters, plus the whole of Canadian Northern Domestic Airspace. The Southern AMU is the matching circle around the magnetic South Pole.<\/p>\r\n\r\n<p>Inside those circles the variation between true and magnetic north does not just grow large. It becomes absurd. The FAA\u2019s own application guide offers the cleanest illustration of the problem anyone has written down.<\/p>\r\n\r\n\r\n<div style=\"background:#f8f9fa;border-left:4px solid #5C91FF;padding:20px 22px;margin:18px 0 24px;font-size:16px;line-height:1.7\"><em>&ldquo;When flying between the magnetic North Pole and the true North Pole, a heading of true north results in a magnetic heading of south (a magnetic variation of 180 degrees).&rdquo;<\/em><div style=\"margin-top:10px;font-size:14px;color:#555\"><strong>FAA Flight Technologies and Procedures Division<\/strong> &mdash; B040 and B055 Application Guide, Version 1.0, 15 August 2025<\/div><\/div>\r\n\r\n\r\n<p>The fix is to stop using magnetic north altogether. Aircraft cleared for polar operations must be able to switch their heading reference from magnetic to true, either by a crew selection or automatically by latitude, and the operator has to document which. In Canadian Northern Domestic Airspace every heading and track is given in degrees true as a matter of course. Controllers there simply do not use magnetic.<\/p>\r\n\r\n<p>There is a second, subtler trap that starts well before the compass fails. Above about 67 degrees of latitude the meridians converge tightly enough that a great-circle course changes its true heading very quickly for very little movement across the ground. The FAA\u2019s warning is that small errors there develop into very large navigation errors over extremely short distances. This is also a moving target: the magnetic North Pole is drifting north-northwest at roughly 45 kilometres a year, so the shape of the unreliable zone changes decade by decade.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/09\/sas-boeing-737-longyearbyen-svalbard-airport-78-north.jpg\" alt=\"SAS Boeing 737 boarding at Longyearbyen, Svalbard\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">A scheduled SAS Boeing 737 at Svalbard Airport Longyearbyen, at 78 degrees north \u2014 the latitude where the FAA\u2019s North Polar Area begins.

ASTM D 1655, the international jet fuel standard, sets a maximum freeze point of \u221240 \u00b0C for Jet A and \u221247 \u00b0C for Jet A-1. Those are ceilings. A given batch is usually better, and the operator is expected to know which.<\/p>\r\n\r\n<p>Polar air at cruising altitude is routinely colder than that, and the fuel in a wing tank keeps cooling for hours. So every polar operator has to hold a fuel-freeze strategy and a procedure for monitoring fuel temperature in flight, either by applying the ASTM limits directly or through an FAA-accepted monitoring programme that gives equivalent protection.<\/p>\r\n\r\n<p>What makes this genuinely interesting is the list of things a crew can actually do about it in the air. The FAA names three. Climb or descend into warmer air. Deviate off course towards warmer air. Or increase Mach number \u2014 which works because flying faster heats the skin of the aircraft, and the fuel behind it, through friction. A polar crew watching a fuel temperature gauge creep downwards has the option of solving it by going faster.<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">What it actually takes to get permission<\/h2>\r\n\r\n<p>Appendix P to Part 121 is blunt about the threshold. Except for intrastate operations inside Alaska, no certificate holder may operate an aircraft in either polar area unless the FAA has authorised it. The authorisation is not a formality. Section III lists eight things that must appear in the airline\u2019s operations specifications before a single passenger is carried across either line.<\/p>\r\n\r\n<p>Designated en-route diversion airports, and the standard each must meet at the moment of diversion. A recovery plan for passengers at those airports \u2014 waived only for all-cargo supplemental operations. A fuel-freeze strategy. A plan to guarantee communications. A dedicated minimum equipment list. A training plan. A plan for mitigating crew radiation exposure during solar flare activity. And, last on the list and the one that sticks in the mind, a plan for carrying at least two cold-weather anti-exposure suits aboard, to protect crew members during outside activity at a diversion airport in extreme conditions. The FAA will let an operator off that one if the season makes it unnecessary.<\/p>\r\n\r\n<p>The passenger recovery plan is where the abstraction stops. It has to cover food, shelter and continuing safety, a method of getting everyone off the aircraft safely in bad weather, medical care, communications, and transport to extract passengers and crew \u2014 with execution and completion expected within 48 hours of the diversion. Two days is the planning assumption for how long people might be sitting on an ice runway.<\/p>\r\n\r\n<p>None of it is granted on paperwork alone. An operator has to pass an FAA tabletop exercise and then fly a validation flight including a simulated diversion into an approved en-route diversion airport, which is assessed for communications, navigation and surveillance, coordination, facilities, the accuracy of NOTAMs and weather, space weather information and whether the ground equipment there actually works. There is a quietly telling rule attached: the validation flight may carry revenue passengers only if the passenger recovery element has already been validated separately. Rehearse abandoning passengers in Antarctica, and you may not have paying passengers aboard while you do it.<\/p>\r\n\r\n\r\n<figure class=\"wp-block-image size-large\" style=\"margin:0 0 24px;width:100%\"><img decoding=\"async\" class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" width=\"1024\" src=\"https:\/\/migflug.com\/afterburner\/wp-content\/uploads\/sites\/4\/2026\/09\/antarctica-ilyushin-il-76-union-glacier-blue-ice-runway.jpg\" alt=\"Ilyushin Il-76 landing at Union Glacier, Antarctica\" style=\"width:100%;height:auto;max-width:100%;display:block\"><figcaption style=\"font-size:13px;color:#777;text-align:center;margin-top:6px;font-style:italic\">An Ilyushin Il-76 on short final to the Union Glacier blue-ice runway.

Airlines pay that price in the north thousands of times a year and almost never in the south, and the reason is embarrassingly simple: there is nothing on the far side of Antarctica worth flying to.<\/p>\r\n\r\n<p>Look at a globe rather than a Mercator chart. New York to Hong Kong, London to Tokyo, Chicago to Delhi \u2014 the shortest line between the northern hemisphere\u2019s large cities runs over or near the top of the world, because that is where the great circle goes. Cathay Pacific proved it commercially on 5 July 1998, when CX889 flew New York to Hong Kong non-stop over the North Pole in 15 hours, 35 minutes and 53 seconds with 137 passengers aboard, the longest non-stop commercial service flown to that date. The route was called Polar One. The geometry has not changed since.<\/p>\r\n\r\n<p>The southern hemisphere offers no equivalent. The cities that would need an Antarctic crossing to shorten their route \u2014 Perth and Buenos Aires, Cape Town and Auckland \u2014 are either small markets, already well served the other way round, or both. An airline would be buying the entire polar rulebook to save an hour on a route that carries one flight a day. It never pencils out. (For why that shortest line looks so strange on a flat map at all, our <a href=\"https:\/\/migflug.com\/afterburner\/great-circle-routes-why-pacific-flights-curve-north-past-alaska\/\">piece on great circle routes<\/a> works through the geometry.)<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">The flights that do cross<\/h2>\r\n\r\n<p>Which brings us back to the aircraft that ignore all of the above. On 14 July 2023, Qantas flight QF28 from Santiago to Sydney flew to <strong>74.17\u00b0 S<\/strong>, out over the Antarctic coast, purely to dodge a band of headwinds on its normal track. That route regularly runs as far south as 70\u00b0 S in ordinary service. Qantas\u2019s 787s hold a 330-minute extended operations approval, and as Flightradar24 noted at the time, at that figure it is only the centre of the continent that stays out of reach.<\/p>\r\n\r\n<p>One point of pedantry worth making, because the number gets misused: 330 minutes is a type-certification figure for the 787 and an approval granted under Australian rules. It does not appear as a threshold in the FAA\u2019s ladder, which runs 75, 90, 120, 138, 180, 207, 240 and then \u201cbeyond 240 minutes\u201d. What the FAA does do is list, among the areas eligible for that beyond-240 category, the oceanic areas between Australia and South America <em>and the South Polar Area<\/em>. The regulator has a box for Antarctic overflight. Airlines simply rarely tick it.<\/p>\r\n\r\n<p>Then there are the flights that go purely to look. Since 1994 a chartered operation out of Australia has flown day trips over the continent \u2014 now on a Qantas 787-9, previously a 747 \u2014 covering 9,500 to 10,500 kilometres round trip in roughly twelve and a half hours, of which three to four hours are spent over Antarctica itself. Nobody lands. Every passenger is issued two boarding passes and swaps seats halfway, so the window seats are shared out.<\/p>\r\n\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/T0IfIeAKcgk\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div>\r\n<p style=\"font-size:13px;color:#777;text-align:center;margin:-14px 0 24px;font-style:italic\">A full trip report from one of the Antarctic sightseeing charters, filmed from the cabin of a Qantas 787.<\/p>\r\n\r\n\r\n<h2 style=\"padding-top:22px\">The widebody that did land<\/h2>\r\n\r\n<p>On 15 November 2023 a Norse Atlantic Airways Boeing 787-9 registered LN-FNC, named <em>Everglades<\/em>, touched down at Troll Airfield in Queen Maud Land \u2014 the first 787 ever to land in Antarctica. It had staged from Oslo via Cape Town and carried roughly 12 tonnes of research equipment along with 45 scientists to the Norwegian Troll research station. There is no asphalt at Troll. The 787 landed on a 3,000-metre blue-ice runway.<\/p>\r\n\r\n\r\n<div style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;margin:24px 0\"><iframe class=\"skip-lazy\" data-no-lazy=\"1\" loading=\"eager\" src=\"https:\/\/www.youtube.com\/embed\/8Q5VrioZTYk\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0\" allowfullscreen><\/iframe><\/div>\r\n<p style=\"font-size:13px;color:#777;text-align:center;margin:-14px 0 24px;font-style:italic\">Sky News coverage of the Norse Atlantic 787-9 arriving at Troll Airfield on 15 November 2023.<\/p>\r\n\r\n\r\n<p>It is a genuinely impressive piece of flying, and it is also the exception that explains the rule. That flight was a chartered, months-planned, single-purpose operation into a runway operated by the Norwegian Polar Institute, with Norwegian permission, in the Antarctic summer. It was not a scheduled service and it was not a diversion.<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">Runways are not alternates<\/h2>\r\n\r\n<p>This is the part that most explanations miss, and it is the real answer to the question. Antarctica is not short of places to put an aircraft down. It has blue-ice runways, compacted-snow strips and skiways scattered across the continent. What it does not have is a single one of them that an airline dispatcher may write on a flight plan as a diversion airport.<\/p>\r\n\r\n<p>The reference document is the Antarctic Flight Information Manual, maintained by COMNAP, the Council of Managers of National Antarctic Programs. It is not a public document \u2014 access runs through member national Antarctic programmes and carries subscription charges \u2014 and the current release is COMNAP-AFIM-25-04, dated 16 March 2026. Its own caveat is unusually direct.<\/p>\r\n\r\n\r\n<div style=\"background:#f8f9fa;border-left:4px solid #5C91FF;padding:20px 22px;margin:18px 0 24px;font-size:16px;line-height:1.7\"><em>&ldquo;The publication of details of the facilities, services and supplies described in the COMNAP AFIM does not imply any right of use.

A runway you must ask permission to use, weeks in advance, from a national research programme that may have nobody on station, is not an alternate. Appendix P asks for designated diversion airports and the standard they must meet <em>at the time of diversion<\/em>. Antarctica cannot supply that. Everything else \u2014 the compass, the fuel, the suits \u2014 is solvable engineering. The missing alternate is not.<\/p>\r\n\r\n<h2 style=\"padding-top:22px\">And no, there is no forbidden zone<\/h2>\r\n\r\n<p>The question attracts a certain amount of nonsense, so it is worth closing the loop plainly. There is no secret prohibition, no restricted airspace covering the continent, and nothing being hidden at the bottom of the map. The Antarctic Treaty regulates access to the area and COMNAP coordinates who flies where, but both operate in the open and both publish their guidance.<\/p>\r\n\r\n<p>The actual constraints are duller than any conspiracy and considerably more demanding: a compass that stops working, fuel that can freeze, no alternate you are entitled to use, a passenger recovery plan with a 48-hour clock on it, two survival suits in a locker, and a validation flight you have to pass before you go. Airlines cross the Arctic because the geometry pays for all that. In the south, it does not.<\/p>\r\n\r\n<p><em>Sources: 14 CFR 121.7 and Appendix P to Part 121 (eCFR); FAA Flight Technologies and Procedures Division, B040 and B055 Application Guide v1.0, 15 August 2025; ASTM D 1655; COMNAP Air Operations and the Antarctic Flight Information Manual; Flightradar24; South China Morning Post; Norse Atlantic Airways; Antarctica Flights.<\/em><\/p>\r\n\r\n\r\n<style>.mfq{margin:34px 0 8px}.mfq h2{font:26px\/1.3 \"Gilroy semiBold\",Helvetica,Arial,sans-serif;color:#0d1117;padding-top:22px;margin:0 0 6px}.mfq .qa details{border-top:1px solid #5C91FF;margin:0;padding:0}.mfq .qa details:last-of-type{border-bottom:1px solid #e2e7ee}.mfq .qa summary{cursor:pointer;list-style:none;display:flex;justify-content:space-between;align-items:center;gap:16px;padding:22px 26px;font:18px\/1.7 \"Gilroy semiBold\",Helvetica,Arial,sans-serif;color:#0d1117}.mfq .qa summary::-webkit-details-marker{display:none}.mfq .qa summary::after{content:\"+\";font:24px Helvetica,sans-serif;color:#3568e0;flex:0 0 auto}.mfq .qa details[open] summary::after{content:\"\\2013\"}.mfq .qa details:hover summary{color:#3568e0}.mfq .qa .a{font:16px\/1.7 \"Gilroy regular\",Helvetica,Arial,sans-serif;color:#454e5e;padding:0 26px 24px}.mfq .qa .a a{color:#3568e0}@media(max-width:680px){.mfq .qa summary{padding:18px 14px;font-size:17px}.mfq .qa .a{padding:0 14px 20px}}<\/style>\r\n\r\n\r\n<section class=\"mfq\"><h2>Frequently Asked Questions<\/h2><div class=\"qa\"><details open><summary>Why don\u2019t planes fly over Antarctica?<\/summary><div class=\"a\">Aircraft do cross Antarctica, but almost never on scheduled airline services. The reason is not a ban. It is that no Antarctic runway can be used as a planned diversion airport, because every facility there belongs to a national research programme and requires prior permission. Without a usable alternate, an airline cannot meet the diversion requirements that Appendix P to Part 121 imposes on polar operations.<\/div><\/details><details><summary>Where does the South Polar Area officially begin?<\/summary><div class=\"a\">Under 14 CFR 121.7 the South Polar Area is the entire area south of 60 degrees South latitude. That is the same line as the Antarctic Treaty Area, which covers everything between 60 and 90 degrees South. The North Polar Area, by contrast, begins much further from its pole, at 78 degrees North.<\/div><\/details><details><summary>Why do planes fly over the Arctic but not the Antarctic?<\/summary><div class=\"a\">Because of where people live. The shortest routes between the large cities of North America, Europe and Asia run over or near the North Pole, so airlines are paid back for the cost of polar approval thousands of times a year. In the southern hemisphere no major city pair is meaningfully shortened by crossing Antarctica, so the same costs buy almost nothing.<\/div><\/details><details><summary>Does a compass work at the poles?<\/summary><div class=\"a\">Not reliably. A magnetic compass senses the horizontal component of the Earth\u2019s magnetic field, which shrinks towards zero near each magnetic pole. The FAA treats the compass as unreliable once horizontal field strength falls below 6,000 nanotesla, which covers roughly a 1,000 nautical mile radius around each magnetic pole. Aircraft flying there switch their heading reference from magnetic to true.<\/div><\/details><details><summary>Can jet fuel freeze on a polar flight?<\/summary><div class=\"a\">It can, which is why every polar operator must hold a fuel-freeze strategy and monitor fuel temperature in flight. ASTM D 1655 caps the freeze point at minus 40 degrees Celsius for Jet A and minus 47 for Jet A-1. If fuel temperature approaches the limit, a crew can climb or descend to warmer air, deviate off course, or increase Mach number, since flying faster warms the airframe.<\/div><\/details><details><summary>Has a Boeing 787 ever landed in Antarctica?<\/summary><div class=\"a\">Yes. On 15 November 2023 a Norse Atlantic Airways Boeing 787-9 registered LN-FNC landed at Troll Airfield in Queen Maud Land, the first 787 to do so. It carried about 12 tonnes of research equipment and 45 scientists, and it landed on a 3,000 metre blue-ice runway rather than a paved one.<\/div><\/details><details><summary>How far south has a passenger airliner flown?<\/summary><div class=\"a\">Qantas flight QF28 from Santiago to Sydney reached 74.17 degrees South on 14 July 2023, overflying the Antarctic coast to avoid strong headwinds on its usual track. That route normally runs as far south as about 70 degrees. Qantas 787s hold a 330-minute extended operations approval, which leaves only the centre of the continent out of reach.<\/div><\/details><details><summary>Are there commercial flights over Antarctica you can book?<\/summary><div class=\"a\">There are sightseeing charters. Since 1994 day trips have operated from Australian cities over the continent, currently using a Qantas Boeing 787-9, covering roughly 9,500 to 10,500 kilometres in about twelve and a half hours with three to four hours spent over Antarctica. The aircraft does not land, and passengers swap seats halfway so everyone gets a window.<\/div><\/details><details><summary>Is Antarctica a no-fly zone?<\/summary><div class=\"a\">No. There is no prohibition on flying over Antarctica and no restricted airspace covering the continent. The Antarctic Treaty governs access to the area and COMNAP coordinates air activity, both openly. What limits airline traffic is the absence of usable diversion airports, not any ban.<\/div><\/details><details><summary>What survival equipment must a polar flight carry?<\/summary><div class=\"a\">Appendix P to Part 121 requires at least two cold-weather anti-exposure suits aboard to protect crew members working outside at a diversion airport in extreme conditions, and the FAA also looks for an expanded medical kit.

The North Polar Area, by contrast, begins much further from its pole, at 78 degrees North.\"}},{\"@type\":\"Question\",\"name\":\"Why do planes fly over the Arctic but not the Antarctic?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Because of where people live. The shortest routes between the large cities of North America, Europe and Asia run over or near the North Pole, so airlines are paid back for the cost of polar approval thousands of times a year. In the southern hemisphere no major city pair is meaningfully shortened by crossing Antarctica, so the same costs buy almost nothing.\"}},{\"@type\":\"Question\",\"name\":\"Does a compass work at the poles?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Not reliably. A magnetic compass senses the horizontal component of the Earth\u2019s magnetic field, which shrinks towards zero near each magnetic pole. The FAA treats the compass as unreliable once horizontal field strength falls below 6,000 nanotesla, which covers roughly a 1,000 nautical mile radius around each magnetic pole. Aircraft flying there switch their heading reference from magnetic to true.\"}},{\"@type\":\"Question\",\"name\":\"Can jet fuel freeze on a polar flight?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"It can, which is why every polar operator must hold a fuel-freeze strategy and monitor fuel temperature in flight. ASTM D 1655 caps the freeze point at minus 40 degrees Celsius for Jet A and minus 47 for Jet A-1. If fuel temperature approaches the limit, a crew can climb or descend to warmer air, deviate off course, or increase Mach number, since flying faster warms the airframe.\"}},{\"@type\":\"Question\",\"name\":\"Has a Boeing 787 ever landed in Antarctica?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. On 15 November 2023 a Norse Atlantic Airways Boeing 787-9 registered LN-FNC landed at Troll Airfield in Queen Maud Land, the first 787 to do so. It carried about 12 tonnes of research equipment and 45 scientists, and it landed on a 3,000 metre blue-ice runway rather than a paved one.\"}},{\"@type\":\"Question\",\"name\":\"How far south has a passenger airliner flown?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Qantas flight QF28 from Santiago to Sydney reached 74.17 degrees South on 14 July 2023, overflying the Antarctic coast to avoid strong headwinds on its usual track. That route normally runs as far south as about 70 degrees. Qantas 787s hold a 330-minute extended operations approval, which leaves only the centre of the continent out of reach.\"}},{\"@type\":\"Question\",\"name\":\"Are there commercial flights over Antarctica you can book?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"There are sightseeing charters. Since 1994 day trips have operated from Australian cities over the continent, currently using a Qantas Boeing 787-9, covering roughly 9,500 to 10,500 kilometres in about twelve and a half hours with three to four hours spent over Antarctica. The aircraft does not land, and passengers swap seats halfway so everyone gets a window.\"}},{\"@type\":\"Question\",\"name\":\"Is Antarctica a no-fly zone?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. There is no prohibition on flying over Antarctica and no restricted airspace covering the continent. The Antarctic Treaty governs access to the area and COMNAP coordinates air activity, both openly. What limits airline traffic is the absence of usable diversion airports, not any ban.\"}},{\"@type\":\"Question\",\"name\":\"What survival equipment must a polar flight carry?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Appendix P to Part 121 requires at least two cold-weather anti-exposure suits aboard to protect crew members working outside at a diversion airport in extreme conditions, and the FAA also looks for an expanded medical kit. The operator must additionally hold a passenger recovery plan, with recovery expected to be completed within 48 hours of a diversion.\"}}]}<\/script><div style=\"background:#f0f4ff;border-left:4px solid #5C91FF;padding:16px 20px;margin:32px 0 8px\"><p style=\"margin:0 0 8px;font-weight:600;color:#333\">Related Posts<\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/great-circle-routes-why-pacific-flights-curve-north-past-alaska\/\">Great Circle Routes: Why Pacific Flights Curve North Past Alaska<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/operation-deep-freeze-antarctic-aviation-lc-130-pegasus\/\">Operation Deep Freeze: 70 Years of US Aviation in Antarctica<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/etops-explained-engines-turn-or-passengers-swim\/\">ETOPS Explained: Engines Turn or Passengers Swim<\/a><\/p><p style=\"margin:4px 0\"><a href=\"https:\/\/migflug.com\/afterburner\/europe-most-extreme-airports-highest-steepest-shortest\/\">Europe\u2019s Most Extreme Airports: Highest, Steepest, Shortest<\/a><\/p><\/div>\r\n","protected":false},"excerpt":{"rendered":"<p>A Boeing 757 sits on the Antarctic ice at Union Glacier.
